Cam breakin procedure :
Inline 4.0/2.5
IMPORTANT INFORMATION
If these guidelines are not adhered to it will VOID your warranty.
· Use moly paste on cam lobes and lifters. ARP, Comp, Lunati, etc.
· Use 6 quarts of 15/40 Rotella oil, VR1 Racing Oil, or Kendell Racing Oil AND 1 quart of Lucas Engine oil stabilizer or a zinc additive.
· Set distributor according to Mopar installation manual so that vehicle is ready to fire.
· As soon as vehicle starts – rev engine between 1800and 2500rpm and run for 30 minutes total.
· You may stop and check for leaks, cooling, etc.
· When you finish running it for 30 minutes, spin a new oil filter on the engine.
· Run vehicle between 200-250 miles. Then change oil. Use same type of oil for the first 1500 miles. We recommend a half a quart of Lucas with every oil change.
Here is Golden's procedure:
Start the engine and make sure you have oil pressure and a good idle for 15-20 seconds without using any throttle. If it doesn’t idle well, you need to shut the engine down and determine the cause of the problem before performing the cam break-in. If this occurs, call the Golen tech line @ 866-501-1242, Monday through Friday, 9am to 5pm Eastern time.
Assuming oil pressure and idle are good, bring the engine up to 2000 rpm. You will keep the engine at 2000 rpm for 20 minutes watching for oil or anti-freeze leaks, oil pressure, and ngine temperature. Also listen for general engine operation. The lifters may take up to 20 minutes to complete pump-up and during this time may make some noise.
If anything needs to be sealed or repaired during break-in, or if the engine overheats, shut the engine down, note how much time is left for the break-in, and repair the issue. Then start the engine back up and continue break-in.
After the cam break-in has been completed, you need change both the oil and the oil filter. After the oil and filter have been changed, you may then perform the final inspection steps in “
Startup Guidelines” and further adjust your timing.
With that all said due to my intake manifold not sealing properly my headers got RED HOT. Now granted I only ran it for 2-3 minutes like this. I can't say what the long term affects this will have on the headers.
But I've seen this note on many web sites.
Warning.
NEVER break in a new or rebuilt engine with ceramic coated headers. Excessive heat will damage the coating and void the warranty. When you break in a new camshaft, lifters, and piston rings, excessive heat is produced.
